Water reservoir

The water reservoir is filled through one inlet 4 hours later than both together, then another inlet 9 hours later. For how long is filled by each separately?

Correct answer:

a =  10 h
b =  15 h

Step-by-step explanation:

a1 + b1 = s1 s = a+bab  a  = 4 +s b  = 9 + s  s(a+b) = ab  s(4+s+9+s) = (4+s)(9+s) s2 = 36  s=36=6 h  a=4+s=4+6=10 h
b=9+s=9+6=15 h
